I went in to pick out a new pair of running shoes even though I couldn't buy them for a few more weeks. The employee helped me determine what types of shoes would be best and even helped me find quality shoes for a low price. He made sure the fit was correct and that I would be comfortable running, which was a concern returning from an ankle stress fracture.
Updated: went back in to actually buy the shoes I picked out and everyone was so helpful again! They made sure I got the right size and fit since I was in between sizes and assured me that if I tried them out and don't like them right away I can bring them back!
